DOOR BUFFER.

Application filed November 17, 1924. Serial No. 750,426.

To all whom it may concern:

Be it known that I, WILLIAM MARSHALL, a citizen of the United States ofAmerica, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements in DoorBuffers, of which the following is a specification, reference being hadtherein to the accompanying drawing.

This invention relates generally to buffers and refers more particularlyto those designed for cushioning doors and the like.

One of the essential objects of the invention is to provide a simple andinexpensive buffer of this type that may be easily and quickly attachedto a metallic door jamb.

Another object is to provide a buffer hav-- ing abutment faces thatextend transversely of each other so that the door may be cushioned inseveral directions.

A further object is to provide a buffer that is preferably formed ofresilient material and is of uniform cross section throughout its lengthso that it may be cut from a long strip of the desired shape.

With the above and other objects in view the invention consists incertain novel features of construction, combinations and arrangements ofparts as will be more fully described and articularly pointed out inthe'appended c aims.

In the accompanying drawing;

Figure 1 is a perspective view of a door jamb with a buffer embodying myinvention applied thereto. I

Figure 2 is a horizontal sectional view taken on the line 2-2 of Figure1.

Figure 3 is a rear elevation of the buffer.

Referring now to the drawing in which like characters of referencedesignate corresponding parts throughout the several views, the numeral1 designates a door jamb, preferably of a vehicle body of the closedtype. This jamb may be any shape desired, but is preferabl formed ofsheet metal and is provided at Its inner edge with a lateris preferablyally extending flange 2.

The buffer 3 may be formed of any suitable yieldable material such asrubber, but L-sha e in cross section so that the inner slde an rearfaces 4: and 5 respectively thereof will fit snugl against the jamb andlateral flange thereo when the parts are assembled. As shown in Figure2, the lateral portion 6 is considerably extends longitudinally thereofand is en- I gageable with a vertically extending substantiallyrectangular shaped opening 11' in the side of the door jamb.

The buffer is positioned upon the door jamb by first inserting'the rib 8into the opening 9 in the lateral flange 2 and then forcing the bufferinwardly so that the rib 10 will project through the opening 11 in theside of the door jamb. The inner and rear faces 4 and 5 respectively ofthe buffer will then be seated snugly against the side and flange of thedoor jamb. Due to the angular formation, the ribs 8 and 10 respectivelyof the buffer will not become accidentally disengaged from the openings9 and 11, hence the buffer will be anchored firmly in place.

From the foregoing description it will be readily apparent that thelateral portion 6 of the buffer will effectively absorb the shocksincident to closing the door. When the door is closed, the main portion7 will absorb any vibrations caused by the door being urged toward thejamb and the lateral portion 6 will then absorb any vibrations caused bythe door being urged inwardly beyond the lateral flange 2 resulting inany weaving or twisting action to which the vehicle body may besubjected while in motion. Hence the angular formation of my buffer is avery important feature that possesses many advantages over other rubberbuffers now in use.

Inasmuch as the buffer is of uniform cross section throughout itslength, it will also be readily apparent that individual buffers can bereadily made by cutting a lon strip of resilient material of the propers hape into the desired lengths. Thus the manufacture of such buffers issimplified considerably.

While it is believed that from the foregoing description the nature andadvantages of the invention will be readily apparent, I desire to haveit understood that I do not limit myself to what is herein shown anddescribed, and that such changes may be resorted to when desired as fallwithin jamb having a lateral flange, of a door bufi'er having a portionseating against the outer face of the jamb, and having a portion seatingagainst the outer face of the flange, and projections extendin from theportion aforesaid of saidbu er extending through said jamb and flangerespectively.

2. A door buflt'er having portions extending transversely of each other,each portion having a longitudinally extending rib projecting therefrom,the rib on one portion being disposed in a plane at substantially rightangles to the rib on the other portion.

3. A door bufi'er comprising a resilient body of substantially L-shapein cross section having a laterally extending rib and, a

, g'earwardly extending rib projecting there- 4. The combination with adoor jamb having a Wall provided with a lateral flange, of a door buffercarried by the janib including a resilient block having divergingportions, one portion of said block being secured to the wall aforesaidof said jamb, and the other portion of said block being secured to saidflange.

5. The combination with a door jamb having diverging walls, of aresilient buffer .laving diverging portions seated against the divergingwalls aforesaid, each of said portransversely of the adjacent wall ofsai pillar.

In testimony whereof I aflix my signature.

WILLIAM MARSHALL.
